my girl can roll over when she is just 3 months old and then she can turn back by 4-5 months.
during this holiday, i helped her to do more exercises. she looks like to doing push up and start crawling la ! she can sit for longer time by herself now. when i hold her standing up, she is very happy and stepping slowly.
i am a working mom but every night, i will play with my girl. when i am sure that she is strong enough to do certain posture, i will ask my maid to do the same in day time.
hi hi, i am very lucky because my girl is very strong in bone. by 2 months old, when i turned her over, she could hold her neck for more than 5 minutes without taking a rest ! thinking about what i ate when i was pregnant, just a box of calcium high milk ! so everything is unexpected.
if you think your baby is not so active, you have to teach her very patiently.
one last word : don't give them too many pcs of clothes and dress like a ball, it will be difficult for them to move. even when it's cold, i don't let her wear socks at home because it's very slippery and difficult to crawl. use the heater la.
